White Organic Light-Emitting Diodes with Evenly Separated Red, Green, and Blue Colors for Efficiency/Color-Rendition Trade-Off Optimization
Shuming Chen,Shuming Chen,Guiping Tan,Guiping Tan,Wai Yeung Wong,Wai Yeung Wong,Hoi Sing Kwok,Hoi Sing Kwok +7 more
TL;DR: In this paper, a triplet emitter, bis(5-(trifluoromethyl)-2-p-tolylpyridine) (acetylacetonate)iridium(III) (1), was conveniently synthesized and used in the fabrication of both monochromatic and white organic light-emitting diodes (WOLEDs).
Journal ArticleDOI
Towards high-power-efficiency solution-processed OLEDs: Material and device perspectives
TL;DR: In this article, the authors demonstrate current development of s-OLEDs targeting for high power efficiency with emphasis on introducing theoretical and practical significance in simultaneously achieving close-to-unity (∼100 %) exciton emission and low driving voltage realized by advanced interface modification, bipolar-transporting-type host, all-exciton-harvesting emissive material and customized device architectures to integrate their functions.
Journal ArticleDOI
High-performance polymer solar cells based on a 2D-conjugated polymer with an alkylthio side-chain
Chaohua Cui,Chaohua Cui,Zhicai He,Yue Wu,Xiao Cheng,Hongbin Wu,Yongfang Li,Yongfang Li,Yong Cao,Wai Yeung Wong +9 more
TL;DR: In this paper, two 2D-conjugated copolymers were designed and synthesized for the application as donor materials in polymer solar cells (PSCs) and for further investigation of the effect of alkylthio side chains on the photovoltaic performance.
Journal ArticleDOI
Solution‐Processible Multi‐component Cyclometalated Iridium Phosphors for High‐Efficiency Orange‐Emitting OLEDs and Their Potential Use as White Light Sources
TL;DR: In this paper, the synthesis and photophysical studies of several multifunctional phosphorescent iridium(III) cyclometalated complexes consisting of the hole-transporting carbazole and fluorene-based 2-phenylpyridine moieties are reported.
Journal ArticleDOI
Efficient Organic Light‐Emitting Diodes based on Sublimable Charged Iridium Phosphorescent Emitters
TL;DR: In this article, the synthesis and characterization of two new phosphorescent cationic iridium(III) cyclometalated diimine complexes with formula [Ir(L) 2 (N-N)] + (PF 6 - ) (HL=(9,9-diethyl-7-pyridinylfluoren-2-yl)diphenylamine); N-N = 4,4'-dimethyl-2,2'-bipyridine (1), 4,7-dimethyl -1,10-phenanthroline (
